Air quality at pedestrian level of two different urban arrays for two wind directions was studied experimentally in a wind-tunnel. Both urban arrays were designed according to typical European cities, formed by courtyard-type buildings with pitched roofs. While the first urban array had constant roof height, the second had variable roof height along all walls. The pollution was simulated by means of ground-level line source in the middle of the urban arrays. The concentrations were measured by a flame ionization detector at horizontal planes at the pedestrian level within the streets and courtyards at the vicinity of the line source. Results of the time and spatial averaged concentration reveal that both wind direction and three-dimensionality of the urban morphology are important parameters influencing the air quality at the pedestrian zones within the urban areas.
